Composing Applications
summary
Braid implements plugin-like extension and inversion-of-control for a chat app by turning features into independent cljc micro-apps that register into a central module system and expose typed extension points as functions. Implementation uses Clojure/ClojureScript, re-frame, figwheel hot-reload, atoms and a central registry; examples extracted include stars, search, embeds and emoji, moving roughly half the code out of core. Hot on/off works in development; runtime production toggling is planned but not yet finished.
